PASTE COMPOSITION AND SOLAR CELL ELEMENT EMPLOYING SAME

摘要

A paste composition capable of sustaining a desired function as the rear surface electrode of a solar cell even if glass frit, which is a substance having an adverse effect on the environment, is not added or the content of such glass frit is reduced, and capable of enhancing bond between an aluminium electrode layer and a p-type silicon semiconductor substrate, and a solar cell element having an electrode formed by using such a composition. The paste composition for forming an aluminium electrode layer (8) on a p-type silicon semiconductor substrate (1) contains an aluminum powder, an organic vehicle and a metal alkoxide. The solar cell element has the aluminium electrode layer (8) formed by applying the paste composition on the p-type silicon semiconductor substrate (1) and then firing the paste composition.
